US Classification:

428 97, 428 95

Abstract:

A carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one olefin block copolymer, especially ethylene based block copolymers An olefin block copolymer is extrusion coated onto the back surface of a primary backing to provide an adhesive backing Additional steps and procedures can include washing or scouring the primary backing and fibers prior to the extrusion step, and utilizing implosion agents The preferred olefin block copolymer is an ethylene based block interpolymers The constructions and methods are suited for making tufted, broad-loom carpet having improved abrasion resistance.

US Classification:

442329, 442361, 442364, 442334, 428373

Abstract:

A bicomponent fiber is obtainable from or comprises an ethylene/α-olefin interpolymer characterized by an elastic recovery, Re, in percent at 300 percent strain and 1 cycle and a density, d, in grams/cubic centimeter, wherein the elastic recovery and the density satisfy the following relationship: Re>1481−1629(d). Such interpolymer can also be characterized by other properties. The fibers made therefrom have a relatively high elastic recovery and a relatively low coefficient of friction. The fibers can be cross-linked, if desired. Woven or non-woven fabrics, such as spunbond, melt blown and spun-laced fabrics or webs can be made from such fibers.

US Classification:

428 95

Abstract:

The present invention pertains to carpet and carpet tile. In one aspect, the carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one non-chlorinated, non-polyvinyl butyral thermoplastic polymer or composition having a specific growth tension at 40 C and a specific residual stress at 25% strain. Additional steps and procedures include washing or scouring the primary backing and fibers prior to the extrusion step, and utilizing implosion agents. The preferred olefin block copolymer are ethylene based block interpolymers. The constructions and methods described herein are particularly suited for making tufted, broad-loom carpet having improved abrasion resistance.
